Question

If initially at rest, are acted upon by same force for the same time, then both bodies acquire the same
1. velocity
2. momentum
3. acceleration
4. kinetic er

Answer 1

Correct Answer - Option 2 : momentum

The correct answer is momentum.

• Since the Force and the duration of time for which it acted are the same, the product of force and time will be the same for both. Since Force×time gives the change in momentum of a body, and they had 0 momenta initially, their final momenta will be the same.
  
• Velocity is the rate at which the position changes.
  • The average velocity is the displacement or position change (a vector quantity) per time ratio.
• Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity.
  • An object is accelerating if it is changing its velocity.
• Kinetic energy, a form of energy that an object or a particle has by reason of its motion.
  • Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
